PROCESS FOR THE EXTRACTION OF IMPURITIES IN WATER USING AMPHOLYTIC POLYMERS OF DIALLYLDIMETHYLAMMONIUM CHLORIDE

摘要

P THIS PROCESS IS CHARACTERIZED BY THE FACT THAT IT CONSISTS IN TREATING WATER CONTAINING IMPURITIES USING SOME PARTS PER MILLION OF A WATER-SOLUBLE POLYMER OBTAINED FROM A MIXTURE OF MONOMERS CONTAINING A MAJOR PART OF DIALLYLDIMETHYLAMMONIUM CHLORIDE AND: / P P A.SOIT OF 5 TO 25 MOLES EITHER ACRYLIC ACID, OR METHACRYLIC ACID; / P P B.SOIT 5 A 25 MOLD OR ACRYLIC ACID, OR METHACRYLIC ACID AND 1 TO 10 MOLES OF ACRYLATE OR HYDROXY METHACRYLATE (CC ALKYL), THE ABOVE PERCENTAGES BE CALCULATED ON THE BASIS OF TOTAL MONOMERS; / P P THIS MONOMER IS CHARACTERIZED BY AN INTRINSIC VISCOSITY OF AT LEAST 0.5. / P
